User-Friendly Navigation System

ABSTRACT

A computer-implemented method includes receiving an input, from a user, in the form of a destination to be navigated to; calculating a route to the destination based on the input; recognizing at least one object on a route taken by the user; processing data from the received input, the calculated route, and the recognized at least one object; and providing an output to the user based on the recognized at least one object, the output being based on natural language processing.

TECHNICAL FIELD

The exemplary embodiments of this invention relate generally to navigation systems and, more specifically, to a navigation system that provides user-friendly instructions to a user of the navigation system.

BACKGROUND

Navigation systems based on signals from global positioning satellite (GPS) systems are generally able to provide locations and estimated directions of vehicles with amounts of error that are within established limits. Such navigation systems may require databases of map information (sometimes through a third party application installed on a user device) that pertains to characteristics of road segments and/or known landmarks catalogued in the databases. These navigation systems may assist in allowing a driver or pilot of a vehicle to keep a vehicle on designated courses, but they are generally lacking in the ability to provide user-friendly instructions that can be followed in complex situations.

For example, it may be difficult for a pilot of a vehicle to follow directions given by a navigation device because there is generally not enough time to look in detail at a screen of the navigation device, or the distance to a turn given by the device is not accurate or hard to discern from the audio command or the provided image. However, if a pilot is provided with instructions that are more human-like, such as “make a right turn after passing the big yellow sculpture after the construction site” or “follow the green car,” the pilot will generally find it much easier to follow the instructions.

The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. All of the embodiments described in this Detailed Description are exemplary embodiments provided to enable persons skilled in the art to make or use the invention and not to limit the scope of the invention which is defined by the claims.

Referring to the Figures, an improved GPS-based navigation system that provides more human-like and user-friendly instructions to a pilot of a vehicle is shown. Instructions that are human-like and user-friendly may be provided to the pilot (e.g., the driver of a car) using neural networks for object recognition and for text-to-speech algorithms. The navigation system may incorporate descriptions of objects that can be seen through cameras or obtained from existing databases.

As shown in FIG. 1, in one example, the GPS-based navigation system may be mounted on any suitable vehicle, such as a car, a truck, or a two- or any multi-wheeled vehicle, or a boat, and may include various hardware components. For example, the GPS-based navigation system (hereinafter referred to as “navigation system” and designated generally by the reference number 100), may be incorporated into a car 110. Various hardware components of the navigation system 100 include, but are not limited to, on-board sensors such as GPS receivers 120 (hereinafter “GPS 120”) and associated antennas, distance sensors and shape detectors (e.g., lasers 130, LIDAR units, radar units 140, and the like) including cameras 150 (e.g., stereo pairs of cameras, RGB cameras, NIR cameras, and the like), on-board processors 160 (e.g., CPU/GPU) for deep neural network analysis on streaming input data, additional processors (e.g., CPU/GPU) for running NLP models to generate spoken instructions, and on-board wireless communication systems (e.g., 4G, wifi, and the like) that may connect to a cloud-based system 190 for downloading updated classification models and sharing local data (such as user-learned preferences).

Referring to FIG. 2A, one example of a network for implementing the navigation system 100 is designated generally by the reference number 200 and is hereinafter referred to as “network 200.” In the network 200, the pilot or driver 210 may provide input 220 to the navigation system 100. Such input 220 may comprise, for example, a desired destination as well as routing options (e.g., fastest, least tolls, least congestion, and the like). The navigation system 100 processes the input 220 and develops an NLP model 230 that provides instructions back to the driver 210. The NLP model 230 developed translates the processed input 220 and outputs the instructions as an NLP output 240 in the form of human-like user-friendly directions to the driver 210.

The navigation system 100 also processes the actions taken by the driver 210 (e.g., the corresponding results of the NLP output 240) and develops a ranking model 250. In the ranking model 250, objects are ranked for use in future NLP outputs 240 to the driver 210. For example, the type of a particular object may be determined from the cameras 150 and/or the distance sensors and/or shape detectors (such as the lasers 130). The dynamic ranking of sensed objects may allow the navigation system 100 to become personalized to the driver 210 and/or the location.

In processing the input 220 to develop the NLP model 230, the navigation system 100 utilizes one or more of object recognition 260, input from a model to determine distances 270, input from the GPS 120, and input from the ranking model 250.

Referring to FIG. 2B, the object recognition 260 may comprise a neural network 290 having neurons 292, 294, 296 that receive inputs into neurons 292 and operate together with the other neurons to mimic thought processes of the human brain. The neurons 292, 294, 296 process data to facilitate the recognition of objects based on shape, for example. Processing of the data may be based on comparative functions. The processed data is output as outputs O₁ . . . O_(N). Examples of neural networks that may be used include, but are not limited to, those based on convolutional networks with multiple hidden layers, fully-connected networks with multiple hidden layers, radial basis function, self-organizing maps, learning vector quantization, recurrent radial networks (Hopfield networks, Boltzmann machines, etc.), and the like. The processed data from the neural network 290 may be used in image analytic algorithms to recognize the type and location of objects in real-time from one or more of the cameras 150 and may incorporate the names of the recognized objects into a natural language description. Image analytic algorithms may include, but are not limited to, color hue detection algorithms, contour approximation algorithms, algorithms that detect parallax from multiple images to calculate distances, or algorithms that fuse visible or infrared spectral channels with scene depth data. Identification of objects within the scene may be achieved via image segmentation algorithms that perform semantic labelling by processing output from a neural network, support vector machine, random forest, or other machine learning classifier software.

In one exemplary embodiment, the image analytics used to recognize objects may comprise an on-board image classifier that provides a substantially immediate response to a streaming input (e.g., inputs I₁ . . . I_(N)) from the one or more cameras 150. The on-board image classifier may compare the streamed inputs as graphical inputs from the one or more cameras 150 to stored images in a database. The navigation system 100 may periodically connect to a cloud server (e.g., cloud 190) to update the database of recognizable objects.

Referring to both FIGS. 2A and 2B, the input to determine distances 270 may also be a streaming input from, for example, the distance sensors and shape detectors (the lasers 130, LIDAR units, or stereo camera pairs). The distance sensors and shape detectors may, for example, emit a signal 280 such as an IR signal that can be input to the model to determine distances 270 and used to determine depth or physical distance. Parameters of the emitted signal 280 may be used with an algorithm to determine how far away objects are. This allows for the NLP outputs 240 as the human-like user-friendly directions to the driver 210 (e.g., “turn right at the red 4-wheel drive vehicle 250 feet ahead”).

The input from the GPS 120 may comprise location information, such as one or more of street address and latitude/longitude coordinates.

In addition, the input from the ranking model 250 can be used by the system to learn in order to improve the directions output to the driver 210. Such learning may occur over time. By comparing a navigation path proposed by the navigation system 100 to an actual path taken by the driver 210, a “quality” component of a given NLP output 240 can be evaluated, and a score associated with the evaluated output instruction can be used to update the ranking model 250 (provide “reinforcement” learning). This allows the navigation system 100 to adapt to an individual driver's preferences and also to adapt to local conditions, such as the specifics of the environment.

Referring to FIG. 3A, a logic flow diagram illustrating an initialization of a driving process using the navigation system 100 is designated generally by the reference number 300 and is hereinafter referred to as “initialization 300.” At block 310 of the initialization 300, a destination determined by the driver 210 may be entered into the navigation system 100. As indicated at block 320, the driver 210 may begin driving. The navigation system 100 may be queried in query block 330 as to whether there is a current driving action. If there is no current driving action, the navigation system 100 may be queried in query block 340 as to whether a destination has been reached. An input to query block 340 may be received as an NLP output (from FIG. 4). If the destination has been reached, feedback 350 may be provided to the driver 210, and the driving process 300 may be terminated. If a destination has not been reached, driving may be continued, as indicated at block 360, and control may be passed back to the query block 330 to inquire as to whether there is a current driving action.

Referring to FIG. 3B, if there is a current driving action in response to query 330 (from FIG. 3A), then there may be a clarification 370 of driving actions. This clarification 370 may be displayed on a display device. In the clarification 370, after designating a destination 375, a route 380 may be pre-planned as a sequence of driving actions. For example, after the driver 210 begins driving, a first driver action 382 may indicate that the driver 210 should turn right and continue driving. A second driver action 384 may indicate that the driver 210 should turn left and continue driving. A third driver action 386 may, indicate that the driver 210 should turn right and continue driving. Subsequent driver actions may indicate further turns until the destination 375 is reached. An optimal audio instruction given by the navigation system 100 for each driver action may be determined dynamically (in real-time) from an output of the navigation system 100.

Referring now to FIG. 4, a logic flow diagram illustrating one exemplary embodiment of an operation of the navigation system 100 is designated generally by the reference number 400 and is hereinafter referred to as “operation 400.” In the operation 400, an input A in the form of an affirmation of a driving action from the query 330 from FIG. 3A may be used to capture 402 an instantaneous/real-time image/video as an input from one or more cameras 150 along with a GPS instruction 404 from the GPS 120. In the capture 402, an image 500 (e.g., image/video 500) as shown in FIG. 5 may be received by the navigation system 100. After the capture 402 of the image/video 500, a correlation 406 between the image/video 500 and the driving action is carried out (live navigation instruction), and an identification 600 and marking may be made of a region of interest 605 (on a map 610) as shown in FIG. 6. As shown in FIG. 6. the captured image/video 500 may be correlated with the GPS instruction 404, and the region of interest 605 may be designated (as indicated by the “x” on the map 610). The map 610 and any marking may be virtual. The identification 600 may be made by overlapping the captured image/video 500 and map 610 to determine the region of interest.

Referring back to FIGS. 4 and 5, after the identification 600, one or more objects may be recognized in a recognition step 408 (FIG. 4). In the recognition step 408, a region of interest 510 may be noted (encircled area in FIG. 5).

Referring back to FIG. 4, data from the GPS 120 and the cameras 150 may be processed in a computation 410. The computation 410 is carried out in which distances between the vehicle in which the navigation system 100 operates and one or more objects 520 recognized in the recognition step 408 and the region of interest 510 may be determined. The computation 410 may incorporate data from any IR sensors 412 associated with the navigation system 100. A result of the computation 410, along with data from the GPS instruction 404, may be inputted to a ranking step 414 in which the one or more objects recognized are ranked (e.g., according to proximity of the one or more objects and any driver preferences). Based on the ranking step 414, a selection 416 may be made to determine an appropriate recognized object (e.g., an object with the highest ranking) to navigate from. This may be the object that the navigation system 100 instructs the driver 210 to follow. Control may then be passed to a guiding step 418, in which the driver 210 may be guided based on the selection 416 using a spoken navigation instruction as NLP output 420. One example of an NLP output 420 may be a user-friendly and easily understandable instruction based on content that may be readily recognized and discerned by the driver 210, such as “Turn, left after the yellow car.” Such an example of an NLP output 420 may be one alternative to a less user-friendly instruction such as “Turn left in twenty meters,” because a yellow car may be more easily recognized than a distance of twenty meters. As shown in FIG. 7, another example of an NLP output 420 may be “Turn right after the construction site where the white truck is.”

Still referring to FIG. 4, the operation 400 may further include a feedback loop 422 in which feedback may be returned to the ranking step 414. In one stream of the feedback loop 422, the actual path taken by the driver 210 may be checked in a checking step 424, and data from the checking step 424 may be fed to a learning step 426 in which driver preferences are learned by the navigation system 100. This learning step 426 may be considered “reinforcement learning.” The results of the learning step 426 may be used in the ranking step 414. In another (optional) stream of the feedback loop 422, feedback 430 may be received from the driver 210, and such feedback 430 may be converted into instructions using NLP in a converting step 432. The results of the converting step 432 may be used in the learning step 426 and subsequently fed to the ranking step 414.

If there is no current driving action in response to query 330 (from FIG. 3A), then no image recognition is obtained, and the driver 210 continues to drive.

In any embodiment, the driver 210 may continue to drive until the destination 375 is reached.

The various blocks shown in FIGS. 2A, 3A, and 4 may be viewed as method steps, and/or as operations that result from operation of computer program code, and/or as a plurality of coupled logic circuit elements constructed to carry out the associated function(s).

Referring now to FIG. 8, a simplified block diagram of various electronic devices and apparatuses that are suitable for use in practicing the exemplary embodiments described herein is shown. For example, a computer 810 may be used to control one or more of the processes as described above.

The PROG 818 may include program instructions that, when executed by the associated DP 814, enable the various electronic devices and apparatuses to operate in accordance with exemplary embodiments. That is, various exemplary embodiments may be implemented at least in part by computer software executable by the DP 814 of the computer 810, or by hardware, or by a combination of software and hardware (and firmware).

The computer 810 may also include dedicated processors, for example a processor 815 that controls the operations of the hardware (e.g., the on-board sensors such as the GPS receivers 120, the distance sensors and shape detectors (e.g., lasers 130, LIDAR units, radar units 140, and the like), the cameras 150 (e.g., stereo pairs of cameras, RGB cameras, NIR cameras, and the like), as well as the on-board processors for neural network analysis and for running the NLP models to generate spoken instructions.

The computer readable MEM 816 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory, and removable memory. The DP 814 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs), and processors based on a multicore processor architecture, as non-limiting examples.

The exemplary embodiments, as discussed herein and as particularly described with respect to exemplary methods, may be implemented in conjunction with a program storage device (e.g., at least one memory) readable by a machine, tangibly embodying a program of instructions (e.g., a program or computer program) executable by the machine for performing operations. The operations comprise utilizing the exemplary embodiments of the method.

In any embodiment, the NLP output 240 may be a result of an execution of computer program instructions (such as PROG 818)), in accordance with the exemplary embodiments.

Based on the foregoing, it should be apparent that various exemplary embodiments provide methods to allow a driver to navigate based on real-time user-friendly instructions.
